Problems solved by technology
Both the keyway and the key are in a round cylinder, which is difficult to process. When the key is fixed, it is deformed by force and the smoothness is reduced. What is more unfavorable is that the sliding friction is proportional to the end face pressure. When the output force of the servo cylinder changes, the sliding damping of the key The force increases accordingly, and their resultant force is the value of the sensor. Electricity cannot distinguish the source of force, resulting in inaccurate output force and inaccurate control.

The invention provides an anti-rotation device for a cylinder rod of a servo pressure cylinder, which comprises a base station and a movable supporting tray. A guide barrel is arranged on the base station. A cylinder is arranged in the guide barrel. The cylinder is in sliding connection with the guide barrel. The first end of the cylinder is connected with a lead screw nut. The lead screw nut is matched and connected with a lead screw in a rotary sliding manner. The lead screw penetrates through the lead screw nut and extends out of the cylinder. The first end of the cylinder is supported on the base station through the movable supporting tray. The second end of the cylinder is supported on the base station through the guide barrel. The anti-rotation device is provided with a bearing, andwalking wheels are enabled to move on the base station. Therefore, the walking resistance is small, and the control is convenient. Meanwhile, when the output force of the servo pressure cylinder is changed, the rolling friction force is not greatly changed. The output force of the servo pressure cylinder is approximate to a sensor value, and the control precision of the servo pressure cylinder force is greatly improved.
Description
technical field [0001] The invention relates to the technical field of servo press cylinders, in particular to a cylinder rod anti-rotation device of a servo press cylinder. Background technique [0002] The cylinder rod anti-rotation device is an important part of the servo cylinder, which cooperates with the lead screw to convert the rotational motion into an axial linear motion. The anti-rotation device of the servo cylinder is unique: it requires large load, small fit clearance and high smoothness. The output force of the servo cylinder is tens of thousands of cattle, and the component force of the reaction force acts on the anti-rotation device, and the static load is very large; the large fit gap leads to low reverse positioning accuracy of the servo cylinder, and instantaneous impact will also cause the cylinder to prevent rotation The device is damaged; the smoothness of the anti-rotation device directly produces a damping force that is output to the force sensor of...
